Abstract Details

Purpose:

To describe wavefront analysis and  quality of vision in different types of irregular corneas.

Setting:

Hospital Moises Broggi. Consorci Sanitari Integral. Barcelona (Spain).

Methods:

24 eyes of 12 patients with different corneal pathologies (16 eyes with Keratoconus, 4 of them with  stromal ring segments, ,4 eyes with postlasik ectasia one of them cross linked, 2 eyes with corneal queratotomies and 2 eyes with previous DALK were evaluated with Sirius CSO. Patients were divided in 2 groups according to visual acuity: Group 1 (with BCVA ≥ 0.6) and Group 2 (with BCVA < 0.6), parameters of wavefront analysis and quality of vision: Root mean square (RMS), Higher order corneal aberrations (HOA) and Point spread function (PSF) were registered and compared in both groups.

Results:

In Group 1 mean RMS was 2,1914 IC 95% (0.8433-3,5394), mean HOA was 0.8828 IC95% (0,4772-1,288) and mean PFS was 0,2620 IC 95% (0,4772-1,2884). In Group 2 mean RMS was 3,36 IC 95% (2,78-3,93), mean HOA was 1,79 IC 95% (1,52.2,07) and mean PFS was 0,11 IC 95% (0,08-0,14).

Conclusions:

Patients with BCVA ≥ 0.6 had lower RMS, HOA and higher PFS. Parameters of Wavefront analysis and quality of vision obtained from Sirius CSO are useful to quantify  quality of vision in irregular corneas
